DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, faucet unit 10 preferably comprises housing 12, pull-out spray head 14, and flexible connector hose 16. In a conventional hot and cold water installation, faucet unit 10 receives water through hot and cold water supply lines 18, 20 from an external source and directs the hot and cold water through valve 22. Valve 22 is typically manually operated, and most generally mixes hot and cold water in the desired proportions and adjusts the total flow to a desired level. After passing through valve 22, the temperature-adjusted water is conveyed through a water outlet port either inside or under housing 12 that is defined in FIG. 1 by a first connector 24 to which hose 16 is connected. In an installation where only cold ("tap") water is supplied to faucet unit 10, it will be apparent that the mixing function is not performed by valve 22, and cold water alone is accordingly conveyed through housing 12 to first connector 24.

Hose 16 preferably comprises an elongated, flexible, tubular polymeric conduit surrounded by corrugated stainless steel shielding. It will be appreciated upon reading this disclosure, however, that other types of hose construction such as, for example, fiber reinforced polymeric hoses and the like can be substituted for the preferred hose 16 in the replacement faucet sprayer hose installation kit of the invention. As shown in FIG. 1, hose 16 has preselected standard male connector 32 and female connector 26 (more visible in FIGS. 9 and 2, respectively) attached to its opposite ends.

For purposes of the present invention, hose 16 can be made up with any of the available OEM-type male and female faucet connectors already attached to opposite ends of the hose as the "preselected standard" male and female connectors. According to the embodiment shown in FIGS. 1, 2 and 9, applicant has chosen connectors like the Delta® brand faucet connectors for use as the preselected standard male and female connectors 32 and 26, respectively, because of the widespread use of such faucets. When the replacement faucet sprayer hose installation kit of the invention (with hose 16 having Delta®-type connectors as the preselected standard male and female connectors) is used with a Delta® brand faucet unit, no other adaptors are required for installation, and the replacement hose segment can be attached directly to the water outlet port connector 24 of faucet unit 10 and to inlet end 38 of spray head 14.

The replacement faucet sprayer hose installation kit of the invention preferably also comprises a plurality of adaptors that make hose 16 adaptable for use with brands of faucet units having connectors other than those on the Delta® brand faucets (or their structural equivalents, such as Peerless® brand faucets). Other well-known faucet brands include, for example, Kohler, Grohe, KWC, Price Pfister, Euro-Style, Moen, American Standyne, Sterling, and the like. Applicant has developed four adaptors that are each attachable to the preselected Delta® type connectors, and that when used in various combinations, permit the attachment of hose 16 to any of the above-mentioned brands of faucet units presently known that are characterized by pull-out spray heads.

Referring to FIGS. 2-5, adaptor 28 is designed for use in attaching the preselected female standard connector 26 of hose 16 to one of either the faucet or sprayer head of Kohler, KWC, Euro-Style, Moen, American Standyne or Sterling brand faucet units having pull-out spray heads. (It should be noted that in some brands, the spray head is adapted for connection to the end of the hose having the female connector and the water outlet port of the faucet is adapted for connection to the end of the hose having the male connector, while in other brands, the male and female connectors are reversed.)

As shown in FIG. 5, adaptor 28 is preferably made of chrome-plated brass. Adaptor 28 preferably comprises a constant 0.330" inside diameter, longitudinal bore section 40 with a chamfer 42 that flares outwardly at an angle of about 30° near the threaded end 44 to facilitate engagement with the cooperating, inwardly tapered surface 48 (FIG. 2) of connector 26. Threads 46 of adaptor 28 are preferably 1/4-18 IPS compression with a 0.520" major diameter. The unthreaded outer section of adaptor 28 (FIGS. 2-5) preferably comprises annular boss 52 having a width of from about 0.020" to about 0.030" and an outside diameter of 0.390", flange 54 having a width of 0.060" and an outside diameter of between 0.700" and 0.710", and body section 56 having a width of about 0.250" and an outside diameter of about 0.600" with a pair of opposed 17/32" flats 58.

Referring to FIGS. 6-8, adaptor 30 is designed for use in attaching the preselected female standard connector 26 of hose 16 to one of either the Grohe or Price Pfister brand faucet units having pull-out spray heads. Adaptor 30 is preferably made of chrome-plated brass. Adaptor 30 preferably comprises a constant 0.330" inside diameter, longitudinal bore section 60 with a chamfer 62 that flares outwardly at an angle of about 30° near the threaded end 64 to facilitate engagement with the cooperating, inwardly tapered surface 48 (FIG. 2) of connector 26. Opposite end 68 is also desirably chamfered (0.080" rise; 0.030" run) inside and outside as shown. Threads 66 of adaptor 30 are preferably 1/4-18 IPS compression with a 0.520" major diameter. The unthreaded outer section of adaptor 30 is preferably made as for adaptor 28 except that in place of boss 52, adaptor 30 has a forwardly extending nose 70 0.312" in width with a 0.580" outside diameter, and a 0.100" wide, 0.120" deep, recess 72 spaced 0.130" back from end 68.

Referring to FIGS. 9-10, adaptor 34 is designed for use in attaching the preselected male standard connector 32 of hose 16 to one of either the KWC, Price Pfister or Euro-Style brand faucet units having pull-out spray heads. Adaptor 34 is preferably made of chrome-plated brass. Adaptor 34 preferably comprises longitudinal bore section 74 having a 0.330" inside diameter with a 1/32"×30° lead-in chamfer 76 and a 0.030" radius 102 to a 0.540" outside diameter. Outside threads 86 are preferably 18 TPI with a 0.635" major diameter, are spaced back about 0.055" from end 78, and extend to a distance of 0.430" from end 78. The unthreaded outer section 84 of adaptor 34 is preferably knurled, with a width of about 0.490" and an outside diameter of 0.750". Inside threads 80 preferably extend about 0.400" inwardly from end 82, and are preferably cut at 18 TPI with a major diameter of 0.625" to mate with the outside threads of male connector 32 of hose 16.

Referring to FIG. 11, adaptor 36 is designed for use in attaching the preselected male standard connector 32 of hose 16 (FIG. 9) to one of either the Kohler, Grohe, Moen, American Standyne, or Sterling brand faucet units having pull-out spray heads. Adaptor 36 is preferably made of chrome-plated brass. Adaptor 36 preferably comprises longitudinal bore section 88 having a 0.330" inside diameter with a 1/32"×30° lead-in chamfer 90 and a 0.030" radius to a 0.540" outside diameter. Outside threads 100 are preferably cut at 24 TPI with a 0.575" major diameter, are spaced back about 0.055" from end 92, and extend to a distance of 0.460" from end 92. The unthreaded outer section 98 of adaptor 36 is preferably knurled, with a width of about 0.390" and an outside diameter of 0.750". Inside threads 94 preferably extend about 0.400" inwardly from end 96, and are preferably cut at 18 TPI with a major diameter of 0.625" to mate with the outside threads of male connector 32 of hose 16.

In each instance where the foregoing adaptors are used in replacing a hose having connectors other than the preselected standard connectors, the ferrule from the old hose should be removed and placed on the new hose for use with the adaptors.

Although adaptors 28, 30, 34, 36 as disclosed herein are preferred for use with preselected standard connectors 26, 32, it will become apparent that selection of different standard connectors for hose 16 will require an associated modification in the structure of the adaptors.

Other alterations and modifications of the invention will likewise become apparent to those of ordinary skill in the art upon reading the present disclosure, and it is intended that the scope of the invention disclosed herein be limited only by the broadest interpretation of the appended claims to which the inventor is legally entitled.
